Twenty-two species of Strymon are known from the vicinity of Cacaulandia in Rondonia, Brazil, of which 14 are new species. These belong to 5 species groups: the "oreala" group [Strymon megarus (Godart)]; the "ziba" group [Strymon ziba (Hewitson), Strymon thulia (Hewitson), Strymon spinatus new species, Strymon latamaculus new species, Strymon pallidulus new species, Stlymon tholus new species]; "valentina" group [Strymon rotundum new species]; "crossoea" group [Strymon crossoea (Hewitson), Strymon crambusa (Hewitson), Stlymon germana new species, Strymon novasignum new species, Strymon clavus new species, Strymon implexus new species, Strymon inmirum new species, Strymon incanus new species, Strymon faunalia (Hewitson), Strymon halos new species, Strymon conspergus new species, Strymon bazochii (Godart), Strymon diagonalis new species]; and "eurytulus" group [Strymon bubastus (Stoll)]. Tentative subgroups of species are suggested for the "crossoea" group as they occur in Rondonia. A neotype is designated for Tmolus basilides and the name synonymized with Strymon megarus. The "basilides" group of Johnson et al. (1990) is renamed the "ziba" group. Based on lectotype designations and superficial and genital differences, S. ziba and S. thu.lia are elevated to specific status.
The species of Gigantombra and Angulopis encountered in the Caca ulandia area of central Rondonia, Brazil, are reviewed. These include ten species (all new) of Gigantombra (G. microserrata, G. dl:vergens, G. quadramacula, G. ampla, G. fuscafascia, G. silva, G. rondonia, G. obscura, G. pelplexa, G. pUlpura) and one new species of Angulo pis (A. tenuis). Thecla sangala Hewitson (1868) is recognized as having priority over Theela autoelea Hewitson (1863-1878 [1877]), new synonym. Rondonia continues to appear as a center ofthecline endemism and to provide abundant examples of sibling species diversity.
The following changes in nomenclature of some species of Amblyeems Thunberg, 1815, are proposed: A) Elevated to new taxonomic status- A. insuturatus (pic, 1902) from (Spennophagus subflavidus var.insuturatus); A. luteolineatus (pic, 1929) from (Spennophagus luteonotatus var .luteolineatus);A. paulonotatus (pic, 1906) from (Spennophagus luteonotatus var.paulonotatus).

The sting apparatus and pygidium are described for eight of 20 Lordomyrma species and one of five Mayriella species. The apparatus of L. epinotaiis is distinctly different from that of other Lordomyrma species. Comparisons with other genera suggest affinities of species of Lordomyrma to species of Cyphoidris and Lachnomyrmex, while Mayriella abstinens Forel shares unusual features with those of Proatta butteli.
Four new species of Ommatius Wiedemann, the female of O. stramineus Scarbrough, and the male of 0. nigellus Scarbrough from Hispaniola are described. A lectotype for O. gwenae Scarbrough and a neotype for O. cinnamomeus are selected. Notes of previously named species, new records, illustrations of terminalia, and a key to the species are included.
Two new species collected in northwestern Venezuela, Macrelmis milleri aneI M. hayelwe, are described and illustrated by line drawings and scanning electron micrographs. Both species are assigned to the new species group Macrelmis milleri, and characters of the new species group are described. A key to the species of the group is given.
The phylogenetic relationships of the species of Padunielia are analyzed based on characters of larvae, pupae, and adults (mainly male genitalia). The genus is monophyletic and most closely related to Psychomyia, and Metalype in the subfamily Psychomyiinae. Nine species groups are suggested. Eight species, including six new to science, are reported from the People's Republic of China for the first time.
Explaining cross-country differences in growth rates requires not only an understanding of the link between growth and public policies, but also an understanding of why countries choose different public policies. This paper shows that ethnic diversity helps explain cross-country differences in public policies and other economic indicators. In the case of Sub-Ssharan Africa, economic growth is associated with low schooling, political instability, underdeveloped financial systems, distorted foreign exchange markets, high government deficits, and insufficient infrastructure. Africa's high ethnic fragmentation explains a significant part of most of these characteristics.
Thirty four species of Zethus are enumerated from Venezuela, providing known and new locality records. Six new species are described: Z. rubioi and Z. vincenti in the subgenus Zethusculus, Z. carpenteri and Z. milleri in the subgenus Zethoides, and Z. bolivarensis and Z. yepezi in the nominate subgenus. A key to the species of Venezuela is provided. The distribution patterns of Zethus are discussed.
Motyxia Chamberlin is comprised of eight species of bioluminescent xystocheirine millipeds in which the gonopodal solenomere arises at different positions, from basally and subbasally on the acropodite to being fused with the companion acropodal branch and detaching proximad or near midlength. Previous synonymies of Amplocheir Chamberlin and LuminodeslnllS Loomis and Davenport under Motyxia are confirmed as is its assignment to the tribe Xystocheirini, which is redefined. Component species are 111. Iwnw Chamberlin, the type species, monica Chamberlin, sequoiae (Loomis and Davenport), tularea (Chamberlin), sequoia (Chamberlin), pior Chamberlin, porrecta Causey and Tiemann, and tiemanni Causey. Motyxia sequoia is comprised oftwo races, the nominate and sequoia alia Causey and Tiemann; sequoia ollae Causey and Tiemann is properly a subspecies of tularea. 1I1otyxiapiorform secea is an invalid name without standing in nomenclature, and M. tejona Chamberlin, and M. expansa and exilis, both by Loomis, are placed in synonymy under M. monica, the oldest name for the southernmost species, as Polydesllws dissectus Wood is referrable to Xystocheir Cook. The bioluminescence is a continuous, neon-white glow of the entire dorsal surface including the antennae and legs. Its visibility at night suggests a warning function analogous to aposematic coloration. The phenomenon may observe a circadian rhythm, and controlled photoperiod experimentation may be productive.
The endomychid beetle genera Anidrytus Gerstaecker and Epopterus Chevrolat have been confused for many years. This paper discusses the similarities and differences of these genera, describes new species, makes some nomenclatural changes, and illustrates the genitalia for many species. New species described: Epopterus picticollis, E. bioculatus, E. confusus, E. gracilis, E. loretensis, E. anomalus, E. aravacus, E. atriventris, E. crypticus, E. quechuanus, E. callerianus, E. flavonotatus, E. submaculatus, E. parvus, Anidrytus nimbiferus, A. parki, A. compactus, A. gibbosus, A. circumcinctus, A. bechyneorum, A. batesi, A. mexicanus, A. trinitatis, A. major, A. humerosus, A. grandis, A. cardiosoma. New synonymies: E. vacuus Gerstaecker (= E. scalaris Gorham); E. decempunctatus Gerstaecker (= E. bifasciatus Pic); E. variegatus Erichson (= E. decoratus Kirsch); A. contractus Gerstaecker (= A. dolosus Gorham); A. helvolus Gerstaecker (= Ephebus ignobilis Gorham); A. parallelus Gerstaecker (= Ephebus depressus Gorham). Changes in nomenclatural status or combination: Epopterus kirshi Strohecker is reduced to a subspecies of E. partitus Gerstaecker; E. angustatus Strohecker is reduced to a subspecies of E. fasciatus (Fabricius); E. fuliginosus Guerin-Meneville is transferred to Anidrytus.
The siliceous claystone and chert lithologic units of the Triassic-Jurassic chert-clastic sequence are well exposed in the Inuyama, Mt. Kinkazan and Hisuikyo areas of the southeastern Mino Terrane. Twenty-one continuous sections from those areas were investigated in order to establish comprehensive radiolarian biozones and clarify the successive lithologic changes through the Triassic and lowest Jurassic. Twenty new radiolarian zones are established; the lowest two are assemblage zones and the others are defined by the first or last occurrence of index taxa. The definitions are as follows in chronological order: TR 0, Follicucullus Assemblage Zone (early Spathian or older); TR 1, Parentactinia nakatsugawaensis Assemblage Zone (late Spathian); TR 2A, Eptingium nakasekoi Lowest-occurrence Zone (early Anisian); TR 2B, Triassocampe coronata group Lowest-occurrence Zone (early Anisian); TR 2C, Triassocampe deweveri Lowest-occurrence Zone (late Anisian); TR 3A, Spine A2 (possiblly derived from Oertlispongus inaequispinosus) Lowest occurrence Zone (late Anisian) ; TR 3B, Yeharaia elegans group Lowest-occurrence Zone (early Ladinian); TR 4A, Muelleritortis cochleata Lowest-occurrence Zone (late Ladinian); TR 4B, Spongoserrula dehli Lowest-occurrence Zone (late Ladinian to early Carnian); TR 5A, Capnuchosphaera Lowest-occurrence Zone (early Carnian); TR 5B, Poulpus carcharus sp. nov. Lowest-occurrence Zone (early to late Carnian); TR 6A, Capnodoce- Trialatus Concurrentrange Zone (late Carnian to early Norian), TR 6B, Trialatus robustus-Lysemelas olbia gen. et sp. nov. Partial-range Zone (early Norian); TR 7, Lysemelas olbia gen. et sp. nov. Lowest-occurrence Zone (early to late Norian); TR 8A: Praemesosaturnalis multidentatus group Lowest-occurrence Zone (late Norian); TR 8B: Praemesosaturnalis pseudokahleri sp. nov. Lowest-occurrence Zone (late Norian) ; TR 8C: Skirt F (possiblly derived from Haeckelicyrtium takemurai) Lowest-occurrence Zone (late Norian to early Rhaetian); TR 8D: Haeckelicyrtium breviora sp. nov. Taxon-range Zone (early to late Rhaetian) ; JR OA: Haeckelicyrtium breviora sp. nov.-Bipedis horiae sp. nov. Partial-range Zone (Hettangian); and JR OB: Bipedis horiae sp. nov. Lowest-occurrence Zone (Hettangian/Sinemurian) . These zones are correlated to previousy established radiolarian assemblages and zones in Japan and other regions. Age assignment of the zones is also discussed on the basis of the correlation and other available chronological data. The original stratigraphic succession of the Triassic in the studied area, which ranges in age from Early Triassic to Early Jurassic, is more than 100 m in thickness and can be reconstructed in detail. The succession is subdivided into seven units based on lithologic features. Each unit was probably accumulated under a particular sedimentary condition, thus successive changes of paleoceanographic environments during Triassic time can be traced continuously. Nine new genera including Ayrtonius, Blonzella, Braginella, Bulbocampe, Enoplocampe, Lysenzelas, Parvibrachiale, Spongoxystris and Veles, and 47 new species are described herein. A comprehensive list of identified taxa is presented.
The Nearctic members of the genus Oetophorus Foerster are revised. There are four species, 0. pleuralis (Cresson), and 0. obscurus, O. clavatus, and O. maculatus, new species. The name Oetophorus stretchii (Cresson) is placed in synonymy with the name Oetophol'us pleuralis (Cresson). Relationships of the genus with others in the tribe Perilissini and relationships of the species included in the genus are briefly discussed.
The subfamily Epiphloeinae is defined to include fourteen genera as follows: Epiphloeus Spinola; Pilosirus, new genus; Plocamocera Spinola; Iontoclerus, new genus; Arenaria, new genus; Ichnea Laporte; Diapromeces, new genus; Pyticeroides Kuwert; Ellipotoma Spinola; J{atamyurus, new genus; Megatrachys, new genus; Madoniella Pic; Hapsidopteris, new genus; and Teutonia, new genus. The following type-species are described: Pilosirus brunoi, new species; Arenaria chiapas, new species; Diapromeces aclydis, new species; Katamyurus paxillus, new species; Megatrachys paniculus, new species; Hapsidopteris diastenus, new species; and Teutonia nova, new species. Elloplium humerale Klug is designated as the typespecies of Iontoclerus. The genus Madolliella is removed from the subfamily Korynetinae andis declared a senior synonym of Phlogistosternus Wolcott. Neiclmea is synonymized with Pyticeroides. This treatise includes a key to the genera of Epiphloeinae, descriptions of the genera and new type-species, and distribution map for each genus.
Based on his studies of the genus Rubus in the Czech Republic, the author describes classification of brambles from Rubus subgen. Rubus in Europe, its recent history, present state, and current problems. In general, the author follows the adherents of "Weberian batology" which in the last 25 years has assumed European responsibility for attempting to ciassify that particular genus. The thesis that not every bramble plant can be inciuded in the ciassification is accepted. The objective reasons for taxonomic difficulties within Rubus subgen. Rubus are connected with special features of taxogenesis of its members, especially with incomplete apomixis, frequent hybridization, splitting of the progeny into different morphotypes, resexualization, transitory existence of segregants, etc. The progress of the evolution of a new taxon in the given taxonomic group can be ranked: individual bush - local type - regional species - species with an extensive distribution area. When classifying a taxon, alongside sufficient morphological characteristics,
great emphasis should be put on the distribution area; its extent can render possible the taxon to be accepted into the classification scheme. On the basis of experience gained from the Czech Republic, the author has accepted some modifications of the scale for acceptance of plants as species. The basic difference is in lowering the low limit of the extent of the distribution area for regional species, to be acceptable for their lnclusion to the classification, i.e. to 20 km in diameter. In contrast to taxa of other plant groups, species of apomictic brambles with more extensive distribution areas are phytogeographically more important than those with small distribution areas. In spite of the use of stricter requirements for the description of new species in Rubus, it appears that many (distinct) species have been neglected until now, and that the number of species in Rubus subgen. Rubus is continuously increasing. The author stresses the necessity of studying the group ser. Glandulosi in Central Europe and points out the usefulness of cooperation with population ecologists to describe the quantitative representation of taxonomically unclassified bramble plants in the field.
The Sclerocoelus galapagensis group is defined and revised, including the description of S. galapagensis new species from the Galapagos Islands; S. caribensis new species from the Caribbean and adjacent areas; S. brasilensis new species from Brazil, Ecuador, Colombia, and Panama; S. hemorrhoidal is new species from Ecuador and Venezuela; and S. andensis new species from Argentina, Bolivia, and Venezuela. The south Atlantic species Sclerocoelus subbrevipennis (Frey), new combination, is redescribed as a member of the S. galapagensis group, and is considered the sister species to the rest of the species group. A key to species, character matrix, and cladogram are provided.
Several Coleopterists have been asked to revise the family sections, working from diskettes modified and provided from the original "Beetles of the United States." They will rewrite these sections, and will be recognized as the author of the section. They are asked to sign a writing contract with the publisher. Other Coleopterists have been asked to review the family sections of the new book. These persons are acknowledged in the family section text.
